Remove status field from security services API

[Carlos Eduardo]

Description
===========
Currently, the get security service API returns an attribute that does not belong to the security services (status). This was added a while ago for compatibility reasons but there is a note that states we should remove it when it becomes something that isn't being used anymore [1].

We are a couple of releases away from when that note was added, so can drop that from the view.

Steps to reproduce
==================

1. Have a devstack environment on the most recent branch
2. Get the output of the manila share-service-show command

Expected result
===============
It shouldn't have a status field in there.

Actual result
=============
There is a status field in the security service

Environment
===========
1. Ubuntu 20.04

2. No specific backend

3. Issue the manila security-service-show command using the -d flag (debug)
